Answer:
The sound intensity of train is 1000 times greater than that of the library.
Explanation:
We have expression for sound intensity level,
A train whistle has a sound intensity level of 70 dB
We have
A library has a sound intensity level of about 40 dB
We also have
Dividing both equations
The sound intensity of train is 1000 times greater than that of the library.
<span>10 times as much. Since F=m*a, and a is constant, the only thing that affects force is the mass.
In response to the below answer, the acceleration due to gravity does not change. The force due to gravity definitely DOES change depending on the mass of the object. Since the force is what the problem asks for, the answer is 10</span>

The distance between the plates is 7.1 * 10^-7 m
<h3>What is the distance?</h3>
The capacitor is a device that is used to store charges. The capacitor always has a dielectric that is placed between the capacitors that separates them.
Given that;
C = εoA/d
C = capacitance
εo = permittivity of free space
A = cross sectional area
d = distance apart
Cd = εoA
d = εoA/C
d = 8.8 * 10^-12 * 8.89 * 10^-4/1.11 * 10^-8
d = 7.1 * 10^-7 m
